摘要： A multirotor wind turbine (1) comprising a tower structure with a main tower part (2) and at least two arms (3), each arm (3) extending away from the main tower part (2) along a direction having a horizontal component. Two or more rotors (4) are mounted on the tower structure in such a manner that each arm (3) of the tower structure carries at least one rotor (4). A gear arrangement (9) of at least one of the rotors (4) comprises a number of pulleys (10, 11, 13) and a number of belts (16, 17) interconnecting the pulleys (10, 11, 13) in order to transfer rotational movements between the pulleys (10, 11, 13), thereby transferring rotational movements from the hub (5) to a rotating shaft (14) connected to a generator (15).

摘要： A control system for calibrating a wind turbine sensor placed on a component of a wind turbine and related methods are disclosed. The wind turbine includes a rotor having at least one wind turbine blade. The method comprises pitching one or more of the at least one of the wind turbine blades according to a predetermined pitch movement which induces a vibratory motion in the at least one turbine blade. A wind turbine sensor measures a vibratory response signal at least partly caused by the vibratory motion. A characteristic sensor response value is determined from the vibratory response signal. The characteristic sensor response value may be compared to a predetermined sensor calibration parameter to determine whether a difference is greater than a predefined tolerance parameter. In this manner, the wind turbine sensor may be calibrated.

摘要： A method for controlling a multirotor wind turbine is disclosed. A first operational state of each of the energy generating units of the wind turbine is obtained. A difference in thrust acting on at least two of the energy generating units is detected. At least one constraint parameter of the set of operational constraints is adjusted in accordance with prevailing operating conditions and in accordance with the detected difference in thrust, and a new operational state for at least one of the energy generating units is derived, based on the at least one adjusted constraint parameter, the new operational state(s) counteracting the detected difference in thrust. Finally, the wind turbine is controlled in accordance with the new operational states for the energy generating units.

摘要： The invention relates to a wind turbine system comprising a support structure with a plurality of wind turbine modules mounted to the support structure. A control system is arranged to enter a service mode wherein service can be performed in the wind turbine system by applying a first control command to a first subset of wind turbine modules for terminating power production. A second control command is applied to a second subset of wind turbine modules for bringing the second subset of wind turbine modules into an damping mode where each of the wind turbine modules of the second subset is operated and/or positioned to damp vibrations, actively and/or passively, of at least one wind turbine module of the first subset of wind turbine modules.

摘要： A wind turbine system is described comprising a plurality of wind turbine modules, each including a rotor, mounted to a support structure including a tower. In use, each rotor has an associated rotating unbalance that defines an unbalance vector. The wind turbine system includes control means configured to coordinate the rotational speeds of the plurality of rotors to attenuate oscillations of the support structure caused by the rotating unbalance of the rotors. Also described is a method of controlling such a wind turbine system. The method comprises coordinating the rotational speeds of the plurality of rotors to attenuate oscillations of the support structure caused by the rotating unbalance of the rotors.

摘要： A method for erecting a multirotor wind turbine (10) is disclosed. A carrier structure (1, 1a, 1b) is arranged circumferentially with respect to a tower structure (2) and hoisted to an upper part of the tower structure (2), using a hoisting arrangement, such as a wire winch arrangement (3, 4, 8). Furthermore, energy generating units (5) may be hoisted to the carrier structure (1, 1a, 1b) using the hoisting arrangement (3, 4, 8). A similar method for dismantling a multirotor wind turbine (10) is also disclosed. The multirotor wind turbine (10) can be erected or dismantled without the need for an external crane.
